This invention relatos to the construction of a. pile fabric and the main object of the'invention is to provide a novel Construction in which areas of pile Weave a-lternate with' areas of plain Weave.

The object of the invention is further to provide such a type of fabric in which the portions of the ground exposed at the face of the fabric displa-y the warps which form the pile and in which the wefts are not displayed.

The object of the invention is further to provide such a type of fabrio in which those ortions of the ground formed of pl'ain Weave are substantially concealed by the pile.

The object of the invention is further to provide such a type of fabric in which the areas preferably consist of blocks of pile Weave alternating with the blocks of plain Weave ground, the appearance of the face of the fabric is that of substantially rectangular blocks of pile alternating with substantially rectangular blocks of ground composed of pile warps and ground warps with the weft concealed.

A fabric constructed in accordance with this invention produces a very pleasing efiect. By varying the dimensions of the alternating areas a wide variety of patterns may be produoed. Since only the warps appear or show to any extent at the face of the fabric, When lying flat, various efi'ects may be produced by Varying the colors of the ground and. pile warps which, for example, may be of mohair or wool, while the weft, which is ooncealed, may be of cotton.

The invention is herein disclosed in a specific form as a mohair plush or velvet in which the warps composing the pile are of mohair, while the ground warps and wefts are of other suitable fibre, such, for example, as cotton.

Such a fabric, or a fabric embodying the this invention, may be woven by a-ny suitable form of loom, but it is particularly adapted for weaving on a double or two-ply loom wherein two layers of fabric are woven face to face and then separated by severing the pile warp's which extend between the two plies of fabric.

i In the drawings:

Fig. 1 is a pers Weave. embodying the invention, the febric-bein'g shown woven double .and before the two plies trated are separated the various war s and weftsvbeing .shown muchexaggerate as to spacing and proportion's.

Fig. 2 is a view in perspective of a more or less diagrammatic or tonventionalized na.- ture to illustrate the principle of the appear- 'ance of the fabric When viewed from the pile face.

In the construction illustrated, the repeat of the fabric takes place lon'gitudinally thereof by groups of eight wefts and the wefts are numbered in Fig. 1 1 to 8, inclusive. The

ground warps repeat transversely of the fabric in pairs passmg alternately over and under the wefts to form therewith a. regular Weave a-nd these ground warps in Fig. 1 are indicated as 1' and'2'.

e pile warps in the construction illusare also arranged in pairs, these pairs alternating transversely of the fabric with the pairs of ground warps, and these pile warps are indicated as 1" and 2".

The pile warps present W-sections, that is, each section of pile warp as it appears in the ground of the fabric 1s shaped like a W. For example, viewing the pile warp 1" in the upper left-band corner of Fig. 1, it will be seen that, viewing the fabric from the face, it passes under the weft 2, over' the weft 3, under the weft 4 and that' its two arms which form the pile diverge, thus giving it the shape of a W. With the double-ply fabric illas trated, the pile warp 1', after passin under the weft 4 in the *upper ply, passes into the lower ply under the weft 6, over the weft 7, under the weft 8, thus forming a similar W-section in the-lower ply fabric.

The W-sections which, as noted, are arranged in pairs between adjaoent ground' warps, are staggered on a, group of four wefts, that is to say, two adjacent W-sections are concatenated witt. four successive wefts, as, fonexample, W-section of the pile warp catenated with'the wefts 2, 3 ready described, and the other W section 2" of the pair being similarly concatenated with th wetsll, 2 and 3. h l

nt e ower l t e'same iewarpsare lmiarly staggdi-e d and oonc atenated with e our 1" being eonand 4, as tlwefts 5, 6, 7 and 8, the pile wu'p 1' being concatenated with the wefts 6, 7 and 8,

- as already explained, and the other pile warp fabric with the' W-sections of the pile warp'in alternation with the groundwarps being concatenated with the same group of four wefts 'and this repeat may extend to as great a number'of pairs of pile warp sections as may be be de'sired. *There are thus presentecl sections of substantially rectangular shape made u of wefts, pile warps and ground warps aternating both longitudinally and transversely of the fabric with sections of plain Weave made u of. wefts and ground warps. With the dou le-ply fabric illustrated, the alternation in one ply comes just opposite to that in the other ply.

In Fig. 2 the abric illustrated in Flg. 1 is shown in a somewhat diagrammatic and oonyentionalized form with the pile out and looking at the face of the fabric woven as the lower ply in Fig. 1. When such a fabric is beaten up, the groundand pile warps apearing between the diverging arms of the -sections of the pile warps 1 and 2 conceal the weft, so that on the face of the ground v and wefts,

' substantially rectangular sections of plain' lends itself to a wide variety of designs based y =converging arms of adjacent 'the fabnc is made in these sections appears only ground warp shown in Fig. 2 in black and pile warp shown hatched. But between the converging arms pile warps the ground is composed solely o ground warps the weft being shown in Fig. 2 in white. But as the'p11e ormed by the arms of the W-sections of the pile warp flufi' out, these sections of plain Weave made up of weft 'and ground warps underneath the W-sections. of pile warp are concealed. Consequently while ulp of substantially rectangular sections of pi e Weave alternating with Weave, the sections of ground which actually show at the face of the fabric are those sections of ground between the diverging arms of pile wherein the' ground is composed of pile' warps, ground. warps and wefts with the wefts concealed.

r It will thus be seen that this type of fabric upon the dimensions and arrangements of the alternating blocks of pile weave and ground weave and that a variety of color efiects'maylbe produced dependng upon the colors of t e pile and ground warps. It will also be seen'that When the fabric is woven as adouble-ply fabric, there is no waste of pile warp because the pile Weave sections alternate with the plain weaye sections.

Having thus described the invention, what is claimed as new, and desired to be Secured by Letters Patent, is:

1. A pile abric comprising wefts, pile warps and ground warps in which the pile warps and the ground warps alternate in pairs, the groundwarpsof each par passing alternately over and under the successive Weft, in which the pile warps are of W-form concatenated with groups of tour wets sep arated by groups of four wefts unconcatenated with the pile'warps and in which the concatenation of the pairs of pile warps with the wefts is repea t'd transversely of the fabric a plurality of-times with the same groups of four wefts and then alternately with t e intermediate groups of four wefts whereby a checkered efiect is produced with the pile warp in the ground between the diverging arms of the W-sections of the pile warp an with the ground sections unconcatenated with the pile warps substantially concealed by the converging arms of adjacent W-pile warp sections.

2. A pile fabric comprising wefts, ground warps and pile warps consisting of W-sections in which pile areas conceal areas of plain ground and alternate longitudinally of the fabric with areas of plain ounds, the said W-sections being arranged m pairs, one

W-section of which passes under, over and un-- der three successive wefts and the other W- section of which passes under the weft the' i first section passes over, over the next weft and under the fourth successive weft, whereby the pile warps appear on the face of the p ain ground areas etween the diver arms of the W-sections, and the pairs o W sections being spaced no further apart longitudinally of the fabric than will allow the arms ofthe W-sections of successive pile y areas to conceal the intermediate areas of plain ground which contain no 3. A pile abric comprising we ts, round warps and pile warps consisting of -sections which' are arran ed to form substantially rectangular pile b locks, alternating both longitudinally and transversely of the fabile warp.

ric with substantially rectangular blocks of plain 'round, the said W-sectio'ns being arrange in pairs, one W-section oi which passes under, over and under three successive wefts and the other W-section of which passes under the' Weft the first section passes over, over the next weft and under the fourth successive weft, whereby the pile warps appear on theiace of the lain ground in the blocks between the divergm arms of the W-pile sections, and the pile b) aving the construction defined in claim 2, n. which the repeat loncks are spaced no urther apart longitudinally of the fabric than 1pile blocks substantially to conceal gtudinally of the fabric is in groups of eght Wefts With the areas of plam ground containng no pile warps containing four wefts and With these areas substantially concealed by the arms of the W-pile sections of successive pile areas.

5. A ile fabrc comprising the construction de ned in clan 3, in which the repeat longtudinally of the fabric is in groups 01" eight Wefts with the blocks of plain ground M contani'ng no pile warps containing fo'ur wefts.

In testimony Whereof, I have signed my name to this specification.
